-- Information about the crash:
Akregator sometimes crashes, especially when opening page containing flash, when opening more pages quickly after each other and so on... I don't see any pattern in it. Sometimes it happens several times during a day, sometimes, there are days withou any single problem...

The crash can be reproduced some of the time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
